Overview: The Observer Design Pattern is a way to design a subsystem that allows many objects to respond automatically to changes of a particular object that's being "observed". Task: Let's say that we have a bank system and this is a main branch (observed class) and there are three branch of bank (concrete class) where is notification supposed to receive by each of those branch notifySubscribers() method. Objectives: • Create a Class UML Diagrams using the Design Patterns showing the Observer Design Pattern. In java code, Create classes and all attributes and methods for the classes.
Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…

Define a class based on the UML class diagram according to your NSU ID. Choose NewDate if your middle four digits of yaur NSU ID is odd, otherwise choose NewTime. The first constructor initialized with today's date or current time. The second constructor initialized the object with the given string. The separator of the elements may be ","or :. Use split method of String class. The third constructor extract Date or Time elements from the given Calendar object. Codes for extracting information from Calendar object is given below. The other methods are self- explanatory. NewDate day, month, year. int interface» Comparable -NewDate) -NewDate(st String) -NewDate(dt Calendar) -setDate(d,m.y.int:boolean getDateg NewDate - difference(d NewDate): int -compareTo(d:NewDate) int -clone0:Object +1o String0:String *compareTo(NewDate o):int -D interface.

Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…
Explore scenarios where you might need to implement a custom Comparator for a class that already implements the Comparable interface. Provide real-world examples for context.
• Create two subclasses for checking and saving accounts.A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and then implement them. Write a test program that creates objects of Account, SavingsAccount, and CheckingAccount and invokes their toString() methods.
Consider the following UML diagram. Suppose that each of these classes has a getMass () method that returns the mass of the current object (double); that the Star class has a getPlanets () method that returns an array of Planet objects (the planets that orbit this planet); and that the Planet class has a getMoons () method that returns an array of Moon objects (the moons if this planet). All attributes of these classes are private. All methods described above are public. Star 0.. Planet Create a class called SolarMass that has a single class method in it called solarMass (Star theStar) that returns the total mass of the input star (along with the mass of all of that star's planets and their moons). The method returns a double. Any program should be able to call this method. e..* Moon
When one class includes objects that belong to another class, this is known as a whole-part relationship or composition. The conclusion is that a has-a connection exists. Consider the following lengthy assertion: getHireDate(), getYear(), and Outputsales.getHighestPaidEmployee() are some useful functions ().
Write the Movie class. The UML diagram of the class is represented below: 1. Implement the class strictly according to its UML one-to-one (do not include anythingextra, and do not miss any data fields or methods). 2. Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.
When one class includes instances of another class, we say that the two classes are "composed" together. Thus, a has-a connection is established. Have a look at this lengthy declaration: Inputsales.getHighestPaidEmployee(), inputsales.getHireDate(), inputsales.getYear() ().
Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. Create a class called test. The main() method in the test class should create three Cat objects and two Budgie The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your test
